It's a smart move from the tournament bosses because engagement with the youngest fans is assured.
Although some within the organising committee may have wanted more bang out of their buck, the structure should be a winner.
The key could be getting in smartly from the time sales open, under a range of banners, from December 2.
"Take Christchurch for example," Walsh said. "The opening match (New Zealand against Sri Lanka) has just over 18,000 seats. That'll sell out in a heartbeat, so I think there's going to be a lot of disappointed people." We want them to get in and get tickets."
Registering on the official site, www.cricketworldcup.com, enables getting into a pre-sale window ahead of the general release date of February 14.
There will be limits of eight tickets per person for both pool and quarter-final games; and six is the maximum for the semifinals and final at the Melbourne Cricket Ground on March 29.
All monies from ticket sales go to Cricket World Cup 2015 Ltd to be dispersed to Cricket Australia and New Zealand Cricket.
Walsh said the trickiest part of the pricing was around the finals, "in terms of how far do you push the envelope".
"Where we've ended up, we've still kept some exclusivity. If you want to be sitting in the best seat in the house you will be paying more than you'd normally pay for a cricket match.
"But inclusion of families is our key thing."
The draw and dates for the associate members tournament - to be staged in New Zealand in February to find the last two qualifiers for the 14-team event - will be released early next month.
